stagefright: Allow devices to use older widevine blobs

Devices may have widevine plugins built with an older MediaSource
interface.  Trying to use them fails because of the change in
interface in the object (it calls the destructor in the blob when
attempting to call setBuffers).

This commit restores the interface for ! QCOM_HARDWARE devices.

Fixes: JIRA-4944.

Audio stops after seeking AVI clip with MP3 audio (special contents without proper key samples)

During seek in AVI, nearest Sync sample was searched both for
audio and video. Sync samples are useful only in case of
video. We can ignore Sync field for non-video tracks.

Correct the time returned by AudioPlayer::getMediaTime

The change 80a68deec52c9a1b47215ed68526206ec88197f8 was added to
eliminate returning negative media positions.

In the change all negative values of realTimeOffset were discarded.
The value realTimeOffset accounts for the latency and the
number of samples played since last feeding the AudioTrack and is
generally negative. By discarding this value for negative values the
time returned does not account for latency or the number of samples
played.
